Exceptional fighter, unique explosiveness, movement speed, combinations.
He would however have big trouble with Current Wlad whether people want to believe it or not, Tyson did not like to fight Tall guys who could box, Wlad's ring generalship has improved a lot since the Sanders defeat, when his style was far more aggressive and open. Mix in a big physical strength difference and more 1 punch K.O power and it is not an easy fight. Mike could catch him with something big and finish him at any stage before the 8th round though.
Same with Lewis, Ali, et cetera, he would be eating a lot of punches and get thrown about in the clinches and tire, i make him a decent favorite over Vitali, Vitali has chin, real good cheen
But he is very slow and doesn't look good against slick fighters.
Best combination puncher at heavyweight alongside Joe Louis.
